In order to learn to listen to Spirit you have to be able to shut off the 'I will figure this out with thought' attitude, which your mind has because the ego has taken it over. Then you can listen to and expect to get input from Holy Spirit. While your mind is chattering and interfering and trying to be in control, this is harder.
The mind has attempted to create its own authority and to use its own tools, on its own, to be the central orchestrator or life and to decide and figure out everything using thinking. But this thinking mind stands in the way of trusting Spirit. The mind is meant to be a tool that Spirit can use, but when the tool has obtained a 'mind of its own', it is now an interference.
To listen to Spirit, you must be willing to stop trying to be God, to stop using thinking and instead to be quiet and listen. Being quiet makes the mind receptive, rather than a broadcaster. When it is constantly broadcasting and generating thought, it is too busy inventing stuff to actually 'perceive' clearly or to receive spiritual impressions. It has to be quieted or put under restraint, just temporarily even, so that you can shut the hell up (literally, stop engaging hell), and open up to receive from Heaven.
